first off, here's the deal. 37gallon tank. 6 tiger barbs, 2 rosy barbs, and one firemouth cichlid. just added two of the 6 tigers, and they were apparently infected with ich, cause now it's spreading to some of the other tiger barbs.
I am treating the water with CopperSafe. I also have raised the temperature to around 85F.
How long does it usually take for the ich to be destroyed?
How often does ich evade the cure and end up killing the fish? Or if I treat it correctly, will I have no problem?
I am most worried about the Firemouth Cichlid, but so far, he hasn't even shown any white spots. Only the tiger barbs.
